Question

In a Win32 C# App, when I run my application and hit some button I get this error “”Class is not licensed for use” and jumps to this code in my VS….

    if (oUCMRWPTemplate.ResultLayoutExistsInd)
    {
        try
        {
            if (oTextSvc_UnmarshallText == null)
            {
                oTextSvc_UnmarshallText = new SelectTemplate.TextSvc();
            }

            int replyHandle = lReply.Handle.ToInt32();

            sText = new StringBuilder(oTextSvc_UnmarshallText.BuildTextFromSRV(ref replyHandle, moUCMRWPTemplateLoadQual.PageWidth));
        }
        catch { }
    }

Debugger stops at the line that says sText = new StringBuilder….

I was wondering from this point what should I look at to find what is the issue?

Answer 1

I suspect the problem is your moUCMRWPTemplateLoadQual instance. This is likely a third party control which is not properly licensed.

The reason the debugger stops on that line is that is where you retrieve a property (PageWidth) which is obviously checking licensing.
